我有以下数据框:
lp_dat <- structure(list(kmeans_cluster = c("1", "2", "3", "4", "1", "2",
"3", "4", "1", "2", "3", "4"), tc = structure(c(2L, 2L, 2L, 2L,
3L, 3L, 3L, 3L, 1L, 1L, 1L, 1L), .Label = c("NT", "IBD+PBS",
"IBD+Serpin"), class = "factor"), n = c(924, 1389, 0, 652, 924,
0, 0, 0, 110, 1389, 11851, 0)), row.names = c(NA, -12L), class = c("tbl_df",
"tbl", "data.frame"))
我想要做的是平滑情节。下面是我使用的代码:
lp <- ggplot(lp_dat, aes(x = tc, y = n, group = 1)) +
geom_point(color = "blue") +
geom_line(linetype = "solid", size = 0.5, color = "blue") +
ggalt::geom_xspline( size = 0.5, linetype = 'dashed') +
facet_wrap(~kmeans_cluster, scales = "free_y") +
theme_bw() +
xlab("") +
ylab("Count")
lp
请注意,虚线是ggalt::geom_xspline()的预期平滑线。
我打算 x 轴的顺序是:
c("NT", "IBD+PBS", "IBD+Serpin")
因此它们被编码为一个因素。
我怎样才能让它像这样顺利呢?但使用预期的 x 轴顺序:
